UK researchers have found success in dogs’ ability to detect bladder
cancer by smelling urine. In recent testing, six dogs of different
breeds were trained for 7 months to discriminate between urine from
bladder cancer patients and urine from cancer-free patients. While the
dogs’ success was not perfect, it was 41 percent successful versus 14
percent as expected by chance alone. In one case, a subject was
consistently identified as positive for bladder cancer by the dogs,
even though cystoscopy and ultrasound results were negative.
